i have a ferroli F30 condensing combi boiler and of late seem to have a problem when running the hot water, usually when the tap is opened the water runs hot then after a few seconds turns cold. usually the way to fix the problem is to run the shower then the hot water returns i would be grateful if anyone has any suggestsions
hi Dave
I have got the same problem with my boiler,the plummer came round today and the fan and air pressuse switch will need to be changed.only the parts will cost us nearly £200!! you should have someone look at it as it will get worst,last time we left it for too long and it affected our heating as well.Good luck
